The reflective study of these books is essential to this Quest. The student needs to become familiar with the mentalist doctrine of the universe, the mystical awareness of his divine Overself, and the metaphysical concept of Mind as the unchanging, underlying Reality. It will not be enough merely to read the books, however. One must cultivate and develop one's own capacity for thinking out the leading ideas here expressed, while deliberately opening oneself and being receptive to them. Such thinking is, in fact, one kind of meditation exercise which may be very profitably practised.
